Piston questions

[85 318i]

I've got some Mahle 89V44's here, but they seem to be a hemi piston. What is this exactly? I can't find ANYTHING about them. I've emailed a few 2002 guys and they seem to think they're a rare set of high comps... Anyone else have them?

To me they look like the stock 84 pistons. I also found these:

I know that they are a higher compression than later M10 pistons, but this just, it confuses me. Damnit, BMW.

Any numbers cast into the underside? i pistons have part #'s there...never fooled with the older engines.

That looks like a standard 1.8i head piston to me, too...
...clean the dome, and see if you can find any numbers stamped into it...

I agree - standard 1.8 high compression
